I'm not sure how this would help, as previously stated it's allowed for you to play in two different servers, and now-a-days it's allowed for you to play in with yourself/same ip (like a brother sister mother father whatever) in a private server. With a booster if you're playing with the same IP then you don't get any tc (I'm an ex-gm and I asked a current gm to make sure that this is true.) I'd also like to mention that with the same IP, two users playing against each other won't get qi either. Your suggestion isn't as effective as you think it'd be.
So honestly, farming already pretty much requires two computers if you'd like to do it easily. In reality this really wouldn't cut as much down on farming as you'd think it would.
